Patented July 1, 1930 UNITED STATES PATENT. OFFICE KARL E. PEILER, OFWEST HARTFORD, CONNECTICUT, ASSIGNOR TO HARTFORD- EMPIRE COMPANY, OFHARTFORD, CONNECTICUT, A CORPORATION'OF DELAWARE CONNECTION FOBWOVEN-WIRE GONVEYERS Application filed December as, 1928. semi at.328,961.

My invention relates to conveyers and especially to conveyers of thehelically woven wire type, such as is disclosed in a patent to Henry W.Ingle, No. 1,583,046, issued May 4, 1926, the same being a type ofconveyer which is especially adapted for use in leers for annealingglassware.

The alternate sections shown in the abovenam'ed-patent are sometimesadvantageously connected by a rigid straight wire extending laterally ofthe conveyer belt and passing through alternate loops of the differentsections instead of by a curved wire, such asis shown in the patent.When such a method of connection is used, it sometimes happens that theparts of the woven wire conveyer narrow, due to various factors, whilethe connecting wires do not shorten correspondingly, and projections areformed on the edges of the conveyer at the connecting points, which areobjectionable.

In conveyers of the type described in the patent, there is a tendencytoward a lateral contraction of the conveyer, due to the stretchingthereof so that the belt gradually is narrowed. There may also be atendency toward a variation in the width of the conveyer belt due toexpansion and contraction on changes of temperature. Also, thesectionsof diflerent. belts of approximately the same width may varyslightly from the standard.

One of the objects of this invention is to provide a connecting meansfor sections of woven wire conveyers which is capable of being widenedor being narrowed correspondingly according to the widening andnarrowing of the conveyer sections, and thus to eliminate theobjectionable projections and indentations. A further object of thisinvention is to provide a straight Wire connection for alternatesections of helically woven wire conveyer belts, which connection can bemade in standard sizes but nevertheless be adapted to be used withconveyer belts which vary slightly in width from the standard.

Further objects of my invention Wlll appear from the followingspecification and claims.

I have illustrated one embodiment of my invention in the accompanyingdrawing, in which:

- The figure is a view in plan of parts of two conveyer belt sectionsconnected by one form of my improved connection. y

In general, this embodiment comprise two overlapping straight wires eachhaving a loop at one end engaging one of the edges of a woven wire belt,and flattened portions at the other end, each wire being slightly longerthan one-half ofthe width of a standard conveyer belt.

Referring to the drawing, a section of helically woven wire conveyerbelt11 is formed with left-hand spirals or helices and a simi- 5 lar section12 is formed with right-hand helices. Connecting wires 13 and 14 areformed with flattened inner end portions 15 and 16 and with outer loopedends 17 and 18. i The flattened portions 15 and 16 are formed so 7 thatwhen they are in overlapping relationship the two wires act as a singleconnecting wire. The connecting wires are inserted through alternatehelices of the two sections of conveyerbelt so that the two flattenedportions 15 and 16 overlap slightly and so that the loops 17 and 18 areturned within the plane of the conveyer and are there fast'ened to loopsat the edges of one of. the conveyer belt sections.

It is unnecessary that the connecting wires be flattened at their innerends inasmuch as they can be placed side by side in the plane of theconveyer belt. Especially is this true, if each wire is slightly bent atthe inner end. 5

The operation of my invention will be obvious from the abovedescription. As the 'conveyer belt narrows or widens due to stretchingof the belt, expansion, or for any other reason, the connecting wires 13and 14 no overlap more or less so that the overall length of theconnections corresponds exactly to the width of the conveyer belt. It isobvious that this type of connecting wire conforms to any slightvariations from standard in the Width of various belt sections.

It is to be understood that the above described embodiment of theinvention is for the purpose of illustration only, and various changesmay be. made therein without departing from the spirit and scope of theinv'ention.

I claim as my invention:

1. A helically woven wire conveyer comprising a section with aright-hand weave and a section with a left-hand weave, and means adaptedto vary in effective length upon variation in the width of said sectionsfor connecting the said sections to each other. 2. In a helically wovenwire conveyer in which there are a plurality of sections, a plurality ofconnectin wires connecting each pair of adjacent sections, theconnecting wires aving operlapping portions.

3. A connection for sections of conveyer belts, comprising a pair ofsubstantially straight connecters having end portions adapted to overlapto a greater or less degree, whereby to adapt said connecters for usewith sections of different width.

4. In a helically woven wire conveyer in which there are a plurality ofsections of alternate weave, a plurality of connecting wires connectingeach pair of adjacent sections, the connecting wires having overlappingflattened portions.

5. In a helically woven Wire conveyer having a plurality of sections, aplurality of intermediate connecting wires joining each pair of adjacentsections, each of said wires having an overlapping flattened portion.

6. In a helically woven wire conveyer having a plurality of sectionswith alternate weave, means varying in width in accordance withvariations in the width of the conveyer for connecting the alternatesections, each of said means comprising a plurality of connecting wiresconnecting each pair of adjacent sections, each of said wires having aportion flattened and part of the said flattened portion overlapping asimilar portion of another connecting wire.

Signed at Hartford, Connecticut, this 22nd day of December, 1928.
